TYPOGRAPHICAL. Macr-rrnnf This invention relates to typographicalmachines, such as linotype machines of the general organizationrepresented in U. S. Letters Patent to O. Mergenthaler No. 436,532,wherein circulating matrices are released by escapements from a magazineor magazines in the order in which their characters are to appear inprint and then assembled in line, the composed line transferred to theface of a mold, the mold filled with molten metal to form a slug orlinotype against the ma:- trices which produce the type charactersthereon, and the matrices thereafter returned thru a distributingmechanism to the magazine or magazines from which they started.

In these machines, the magazines are usually mounted in such manner thatthey may be quickly removed and rep-laced by other magazines containingdifl'erent matrix fonts. Before removing a magazine, however, it iscustomary to lock the matrices therein; in fact, this is necessary whenthe escapements are separated from the magazine, as otherwise thematrices would be free to escape therefrom. Hence, the commercialmachines are equipped with devices which prevent the removal of thedesired magazine until the matrices have been first locked therein. Insome instances, as when the magazine is lifted out of engagement withthe escapements, the locking devices are arranged to prevent thepremature raising of the magazine; while, in other instances, as whenthe escapements are lowered out of operative relation to'the magazine,the locking devices are arranged to prevent the movement of theescapements as distinguished from that of the magazine. In either case,the lockingdevices referred to are controlled and actuated by matrixlocking means, which in locking the matrices in the magazine releaseitfor removal. There are two kinds of matrix locking means now in use, onebeing in the form of a detachable bar which is inserted and removedendwise thru the edge of the magazine at the right, and the other beingin the form of a permanently at tached bar mounted on the magazine so asto be movable instantly to active or inactive position.

While the detachable bar is cheap to manufacture and presents otheradvantages over bars of the permanent type, serious difficultieshavearisen in its use in certain commercial machines, particularly thoseequipped with auxiliary magazines. In the latter class of machines, theproximity and arrangement of the auxiliary magazines and theirassociated parts inrelation to the main magazines is such that theyinterfere with the regular manipulation of the locking bars, and it isfrequently necessary, in multiple magazine machines, to first raise.either the main-magazines or the auxiliary magazines as a whole fromtheir last adjusted position in order to 1 insert or withdraw thelocking bar and thereafter restore the magazines to their originalposition. As a result of this condition, which isgenerally inconvenientand troublesome, the interchange of magazinesrequires more time than itotherwise would. p

The present invention is intended to obviate these and otherdifi'iculties and contemplates a detachable locking bar which willpresentevery' advantage of the old locking bar but which maybeeflectively employed and freely manipulated in locking and releasing thematrices of the main'magazines on'all machines, including those providedwith auxiliary magazines. To this end, the parts are so constructed andarranged that the locking bar may be inserted and removed thru the edgeof the magazine adjacent the magazine-'locking device, which is locatedat the left instead of'the right side of the magazine or the sideopposite the auxiliary magazines, the bar being formed with an angularofl'set portion which is adapted to engage and-actuate said device asthe bar is moved to and from its active position.

In the accompanying drawings, the invention has been shown merely inpreferred form and byway of example, but obviously many alterations andvariations may be made therein and in its mode of application which willstill be comprised within its spirit. It is therefore to be understoodthat theinvention is'not limited to any specific form or embodimentexcept in so far as such limitations are specified in the claims. v

Referring to the drawings: V Fig. 1 perspective view of a magazine andparts associated therewith showing the application of the presentinvention; and

Fig. 2 is a side elevation, partly in section,

showing the magazine in operative relation to the escapements andassembler throat.

The matrices X, see Fig. 2, are stored'in the channeled. magazine A fromwhich they pass into the assembler throat or raceway B, under control ofthe escapementsG, the latter beingactuated thru the series of pivotedleversC from the regular keyboard mechanism, not shown. The magazine Ais'or may be of. standard construction, thruout, comprising the upperand lower grooved plates A A and right and left hand side bars A A whichlatter sustain the plates in parallel spaced relation. At the front, theplates A A are extended by means of the usual heavier plate sections AA, respectively, which are also fastened to the side bars A A-*, theupper section A being formed with the inner longitudinal groove Aarranged toregister withthe regulartransverse Openings A in the magazineside bars, and the lower section A being recessed or aperturede on itsunder side to receive the grooved portions of the escapement supportingbar C Asshown in Fig. 2, the escapement bar C is fixed tot-he magazinebase frame D, while the magazine is adapted to be lifted out ofengagement therewith preparatory to its removal. Consequently, thesafety locking device herein illustrated is associated with the magazinerather than with the escapements and is intended to prevent the liftingofthe magazine from its base frame until the mat- 'rices'have first beenlocked therein, This device is arranged as usual at the left side of themagazine adjacent the side bar A and consists of a latch or lever Edisposed in the longitudinal plane of the magazine and pivotally mountedin a suitable bracket E fastened to the baseframeD. A light compressionspring E seated in the bracket E and engagingthe latchE, serves tomaintain'the latter resiliently in active position with its rear enddirectly opposedto a finger F risplate F' normally disposed in the planeof the base'frame Din position to directly engage alongitudinal bar Afast to the magazine ribs A Vith this arrangement, by turning the rockshaft F, the cam plate will be swung upwardly and downwardly and,

thru its engagement with the bar A", will raiseandlower themagazinerelatively to the base frame and the escapement bar C The rockshaft F is operated manually as usual by means of a pair ofside arm's Fwhich are detachably mounted on the opposite ends thereof, and maybelocked thereto in-any suit able manner in order to obtainv thepurchase required; These arms are adapted tobank upon lateral;projections D of the base frame D when swung forwardlyto raise themagazine-and, at such time, serve not only to support the magazineduring its removal but also'tofacilitate its replacement. Theforegoingparts and their mode of operation are similar to thoseincorporated in the most recent linotype models and in themselvesconstitute no part of the present invention. For further information,reference may be hadto the McNamara. Patent'No. 1,586,316, dated May 25,19:26.

The present invention is directed specifically to a novel schemeforlocking the matrices in the magazinein such manner as to avoid thedifliculties pointed out in the openin g statement. In the preferredembodiment illustrated", there is employed a detachable bar Gr which canbe inserted into the magaproved bar Gin cross section is similar to theregular detachable bar heretofore used and hence will: fit within theopening A in the magazine side bar A and be properly guided in thelongitudinal groove A of the plate section A? as it is thrust thru orwithdrawn fromthe magazine. At one end, the bar Gris formed with anoffset noseportion G which is arranged to engage the latch E and rock itout of'the path of the finger F as the bar is shoved home, it beingnoted (see Fig. 1)' that the bracket E is recessed or cutaway at Etoiexpose aportion of the latch and permit its engagement by the nose GPreferably, the upper'corner of the latch portion exposed by the recessE is beveled off as at E for the purpose presently to appear. A lug orstop shoulder G formed on the bar G near the offset portion thereof, isadapted to engage the side of the magazine when the rod is shovedinwardly and serves to locate the rod endwise in its active position.

The operation of the parts according to the foregoing arrangement willnow be clear. When it is desired toremove the magazine A, the rod G isfirst inserted therein thru the opening A inthe side barA and pushedtoward the right until the stop shoulder G banksagainst the end of thetop plate section- A to which it is opposed; The matrices arethuslockedin themagazine against escape, and the nose portion G will have-engagedthe latch E and moved the rear end thereof out of the pathof theupstanding fingerF The magazine is'now free tobe lifted safely out ofengagement with the es capements C to the removing position indicated.by the dotted lines in Fig. 2, this operation' being accomplished in themanner before described by means of theside arms F and the cam plate FAs the magazine'is raised, the nose portion G is disengaged fromthelatch E and thelatter is allowed to resume its normal lock-ingposition-under action of the spring E When the magazine is lowered,howeventhe nose G reengages the beveled corner E ofthe latch and by suchengagement cams the latter out of the way so that the magazine mayproperly seat upon the escapement bar C After the magazine comes to reston the base frame I), the side arms F may be removed from the shaft F,if desired, and the rod G withdrawn from the magazine, the latch E thruthe later operation being released and again restored to its activeposition by the compression spring E Having thus described my invention,its construction and mode of operation, what I claim is as follows:
